EXTENSION-DRAWER SUPPORT.

Application filed January This invention relates to an improved eX- tension dra-wer support and seeks, among other objects, to provide a structure which will sustain the drawer for frce sliding movement and will rigidly support the drawer when drawn out its entirelength..

The invention seeks, as a further object, to provide a support embodying means for adjustably elevating or lowering the inner end' of the drawer as well as means for adjustably elevating or lowering the outer end of the drawer so that the drawer may be .vreadilyleveled andmaintained in level position.

Another objectof the invention is to provide a support wherein the drawer will be locked to the support so that the drawer can not become accidentally displaced when drawn out but wherein the drawer may be reacily detached and removed when so ydesire And the invention seeks, as a still further object, to provide a support which will be quiet and smooth in operation and wherein friction will be largely overcome so that the Vdrawer may be shifted with but little etlort.

Other and incidental objects will appear hereinafter. f .c

lReferring now morev particularly to the drawings, I have, for convenience, ,shownA my improved support in connection with a conventional cabinet 10 having side rails 11.

- f A drawer is indicated at 12 'andsince the 21, 1925.` serial No. 3,855.'

drawer is identical, a description of the il- Vlustrated'structure at the left of the drawer will suffice forboth. A s will be understood, I have, in showing the support in connection with a cabinet, kmerely illustrated a typical mounting of the support and, of course, the support may be employed in connection with any other `structure which is formed to contain drawers.

Referring now more particularly to Figure 1 lof the drawings,-I employ a pair vof vertical front and rear end bars 13 and 14 i which are fixed at their ends to the rails 11 of the cabinet 10, and connecting said end bars is a pair of spaced parallel upper and lower track rails 15 and 16 extendinghorizontally between said bars. Rigidly fixed to the rear end bar 14 at a point midwaybetween the rails 15 and 16, is, as. particularly shown in Figure 5, an inwardly projecting stud 17 and pivotally connected at its inner end to said stud is anv extensible arm 18 of v the lazy tong type. Preferably, suitable washers, as indicated at 19.v are arranged between the cross straps of the arm, upon the pivots thereof, so that the straps may freely swing with respect to each other. and rigidly iXed to the free end of one of the outer- Lying between the arm 18 and the track rails 15` and 16 is a carrier 23 in the nature of a plate which is provided with a pair of depending legs 24 and secured to said legsis a pair of horizont-al 'carrier track rails 25 disposed in parallelv relation. Mounted upon the Vcarrier 23 is a pair of spaced lower roll- [ers 26 journaled upon' studs 27 extending through the Carrier and journaled upon a like studV 28, in a plane between the rollers 26, is an upper roller 29. These rollers are preferably of iberor some other approprifate composition so as to eliminate noise and are grooved to fit the confronting edges of the rails 15 and 16, the lupper-roller beingr As shown f.

the stud is Vformed with parallel flat faces 'I disposed to coact with the lower edge of the rail 15 and the lower rollers being-'disposed to coact with the 'upper edge of the rail 16. Thus, these rollers will support the carrier one arm of which depends from said rail,

for free movement along the track rails. Fixed to the carrier adjacent the forward and rear edges thereof are bumpers 30 and 31 which are preferablyof.rubber andfiXed:

to the front end bar 13 is a cleat 32 which, when the carrier is shifted forwardly, will be engaged by the bumper 30 for limiting the carrier in its forward'inovement, theA cleat thus forming a stop for the carrier. Furthermore, this cleat will also serve torreinforce the front end bar and, as shown in `Figure 5, the rear end bar. 14 is also providedwitli like reinforcing cleats 33. Mounted upontlie upper track rail 15 near tliei'ear end thereof, is an angle shaped stop plate 34,

and extending through the other' arm of said plate is a bolt 3T: which is freely accommodated by a slot. 36 insaidrail;l The stop jplate is thus mounted so that the depending arm thereof will coact with the bumper, 31 for limiting the carrier in its rearward movement and, as willbe at once appreciated,

provision is made whereby this plate may be readilyadj usted longitudinally of the rail 15 for varying the rearward'travel of the carrier. Rigidly fixed to the carrier medially thereof is a pivot stud 37 which extends Vthrough" a pair of the cross straps ofthe arm of the drawer 12 near the rear cnd thereof rails25 ofthe carrier 23, and formed in ther L and close to the bottoinof the drawer, is a lever is a roller 39 lilre the rollers 26 and 29.

drawer and fixed upon the-rear end offsaidV lever is a roller 39 likje Lthe rollers 26 and29. The roller 39'is groovedto fit between the forward endof tlielever 38 is a-transverse slot 40 accommodating a clamp screw 41 sunk into the adjacent side of the drawer. Pivoted medially upon the adjacent side of the drawer nearA the forward end'thereof, as well as near the upper edge of the drawer,

is asecond lever 42,'the rear end 'of which is,

as particularly shown in Figures 6 and'7V of the drawings, provided with like notches 43 'nut 47.

and 44. Formed in the forward end of said lever is a transverse slot 45 accommodating I a` bolt 46which extends through' the adjacent side of the drawer and carries a clamping A t its forward terminalt-he lever is further provided with an out-turned thumb lug 48. in mounting the drawer, the arm 18 is first extended.' as shown iirFiguies 21and7`, when the roller 39 of the lever '38 vis inserted between the rails 25 of the carrie'r. The lever 42 is then, asshown iii Figure 7, swung up, while the forward end of the drawerfis slightly elevated". until the,`

mouth of `the notch 43 is disposed'to accommodate the flat sides 220i?4 the stud 20 at the outer end of the arm 18. Thus, the lever= may, then beswung; downwardly slightly to engage the lever with said stud, when the leverissecured by the clamping nut 47. Accordingly, when the outer end of the drawer is released, the stud 2O will lie crosswise of the notch 43 of the lever 42 while the stud will, as shown in Figure 4,'- be retained against endwise movement throughv Said notch by the head 21- of the stud.` Accordingly, the drawer will be locked to the arm 18,and, `asvwill be appreciated, caniiot become accidentally released when the drawer is drawn out.

' As will now be seen in view offthe foregoing, the weight of the drawer-will becommunicated to the carrier andsupportedflo'y'v the carrier rollers in conjunction with the roller 39 of the lever 38,v which latter roller will coact with the rails 25 ofthe carrier to support a portion of the weight ofiv the drawer. moved inwardly or outwardlyandalthough the carrier moves withl the armv 18, still, the

rails 25 are of such lengththat; atyno time,

will the roller 39 become'displaced from between the rails. Furthermore, attention is particularly directed to the fact that' by loosening. the screw 41, the leverv 38 Imay be rocked for raising or lowering' the. inn-erl end of the drawer while by loosening thel nut 47 The drawer mayV thus be easily the lever 42`inav berocled'for raising or? lowering the outer end/ofthe drawer.I The drawer inay thus bereadi'ly leveledt upon the support and adjustment easily made from time to time to main-tain the drawer in level position. i Y

To detach the drawer, the lever 42 'is shifted yto the positionishown in. Figure 7. andthe forward end of the drawer slightlyi elevated, when the lever may be swung 'uptoV disengage the stud 20. The drawer/may'then,'of

course., be pulled" forwardly 'anddisplaced The slo-t 44fin tli'e lever isprovided'so Ythat the lever may be mounted at the right-*side of a drawer instead ofrthe left-.as-'showm when saidislot would be disposedtoengage'- the stud 20 ofthe arm 18 at said vside ofthe drawer. Thus, in practice, no attention need be vgiven the question of inoiinting-tlrelever at a particular side of the drawer.
